I also had this problem. But I have found the root of it.

When using AGI, you usually fetch the callerid from the environment sent
by asterisk when the agi is connected.

If you look around line 737 in res/res_agi.c, you will see the following:

        ast_agi_send(fd, chan, "agi_callerid: %s\n",
S_OR(chan->cid.cid_num, "unknown"));
        ast_agi_send(fd, chan, "agi_calleridname: %s\n",
S_OR(chan->cid.cid_name, "unknown"));

The problem is when your agi script is washing callerid and setting it to
the value fetched by agi_callerid.

I think it's kinda hard to figure if this is a "undocumented feature" or a
bug. In my oppinion, I think its kind of bad by asterisk to say "unknown"
in this caller_id field when all other caller id functions in asterisk
returns an empty string.
